ELEC § 9607

The proponents of an initiative measure shall ensure that any person, company, or other organization that is paid, or who volunteers, to solicit signatures to qualify the proposed measure for the ballot shall receive instruction on the requirements and prohibitions imposed by state law with respect to circulation of the petition and signature gathering thereon, with an emphasis on the prohibition on the use of signatures on an initiative petition for a purpose other than qualification of the proposed measure for the ballot.
